The significance of maintaining a pool’s cleanliness and upkeep throughout the year is something that all pool owners can agree on. Even while maintaining the pool may be a tedious activity, it is unquestionably important because its condition directly impacts the health of individuals who use it. Along with regular cleaning, it is critical to maintain the pool’s hygienic conditions. In line with this, it is a known fact that chlorine is the most important component and chemical for keeping swimming pools clean and safe to swim in. It is also among the common additives in pools and hot tubs that has the capacity to kill algae spores, bacteria, and small insects. There are actually different types of chlorine products you can choose from to add to your pool — from liquid chlorine to chlorine tablets.
While liquid chlorine is usually the type that is chosen to be applied to pools, chlorine tablets are deemed to be a more convenient alternative. This is primarily because of how they are premeasured, dissolve over time, and do not considerably raise chlorine levels in any particular area of the pool. Additionally, swimmers must leave the pool for at least 30 minutes following liquid chlorine treatment; thus liquid chlorine cannot make the same claim.
Before choosing chlorine tablets for your pool, there are a number of things to consider. This includes the kind, size, and rate of dissolution of the tablet, the right quantity of chlorine for the size of the pool, and a few vital safety guidelines. Continue reading to help you choose the best chlorine tablets as part of your swimming pool maintenance.
Type of Chlorine Tablets
Before choosing the best type of chlorine tablets to apply to your pool, it is important to understand the types there are. People can choose from a variety of chlorine treatments to use in a swimming pool or spa, including dichlor and trichlor, which is the most popular option. Other treatments include sodium hypochlorite, lithium hypochlorite, calcium hypochlorite, and lithium lithium hypochlorite.
If the pool’s water filtration system has trouble with high calcium hardness, sodium hypochlorite is a good solution. The treatment is not the best at eliminating germs or algae because it only has 10 to 12 percent chlorine in it. But then, sodium hypochlorite chlorine treatments are non-stabilized, meaning they can degrade in the sun and produce dangerous chloramines that irritate the skin and cause red, irritated eyes.
The chlorine content of lithium hypochlorite is higher, ranging from 28 to 35 percent. This type of chlorine is non-stabilized and is susceptible to UV radiation. However, this enables it to more efficiently maintain the chemical equilibrium of the swimming pool water.
Another pool treatment that is not stabilized is calcium hypochlorite. With a chlorine percentage of roughly 65, calcium hypochlorite is more efficient than both sodium and lithium hypochlorite. Although it is still susceptible to UV radiation and chloramine formation.
Dichlor is a chlorine treatment that, when mixed with cyanuric acid, produces stabilized chlorine that is UV-resistant and inhibits the breakdown of chlorine molecules and the release of chloramines into swimming pool water. These type of products often come in the form of granules rather than solid pills and range in chlorine content from 56 to 62.
The most popular chlorine treatment for swimming pools is triclor. It comes in the form of solid tablets and contains up to 90% chlorine. Another type of stabilized chlorine is found in trichlor chlorine tablets. The treatment will not degrade in direct sunlight or UV light after a tablet dissolves into pool water, reducing the generation of chloramines.
Size of Tablets
There are typically just two sizes of chlorine tablets: little ones with a diameter of 1 inch and larger ones with a diameter of 3 inches. Although the two tablets’ core operating principles are essentially the same, the total effectiveness and outcomes will undoubtedly differ depending on your pool.
1-Inch Chlorine Tablets
1-inch tablets are intended to be used with smaller water bodies, such as hot tubs, spas, and pools. The main benefit of this size is that it dissolves quickly in water, providing an immediate and noticeable result. Additionally, you will notice a rapid rise in your pool’s chlorine level due to the faster rate of dissolution. However, when it comes to large bodies of water with a water capacity of 5000 gallons or more, these tablets are very ineffectual.
3-Inch Chlorine Tablets
An average of 5,000 gallons of water may be treated with a 3-inch chlorine tablet, making them perfect for large pools. Despite the fact that 3-inch tablets dissolve much more slowly, pools with more than 5,000 gallons of water can utilize multiple chlorine tablets. For larger situations, a 3 inch tablet should be chosen instead. These tablets may dissolve a little more slowly, but they are still effective at raising the chlorine levels of huge water bodies.
Both sizes can be used in skimmers, floating dispensers, and automatic chlorine dispensers. Thus, it is important for you to focus on picking the ideal type based on the size of the pool instead of worrying about the right size. But then, this is still a factor.
As you may know, the dissolving speed of a chlorine tablet plays a critical role in its effectiveness and effects on the water body. The exact rate at which a given chlorine tablet dissolves depends on a wide range of variables, including the method of administration, the typical water temperature, the water pressure, the size of the tablet, the kind of pool water, the available filtering system, and many more.
It can be challenging to predict a chlorine tablet’s dissolving pace based solely on product information because variables including application technique, water temperature, water pressure, and tablet size might affect how long it takes to dissolve.
The general rule of thumb is to keep in mind that for the same application, a 3-inch chlorine tablet will undoubtedly dissolve much more slowly than a 1-inch tablet. Whether or not you use a floating dispenser to dissolve the chlorine tablets affects how quickly they dissolve. The overall dissolving time could be shortened by employing a floating dispenser. However, the chlorine density might not be constant across your pool. Consider automatic dispensers instead, which, depending on the size of the tablet, can dissolve chlorine tablets in 2 to 5 hours. These dispensers can also be modified to meet your needs, including speed adjustments.
Every pool, hot tub, or spa has a different level of chlorine. To find out the pH and chlorine content of the water, you must test it using a pool test kit. For the water to be deemed safe, the pH level should ideally be between 7.2 and 7.8, and the chlorine level should fall between 1 and 3ppm (parts per million).
Depending on the manufacturer, a 3-inch chlorine tablet will typically treat 5,000–10,000 gallons of water. However, only around 350 gallons of water may be treated with a single 1-inch chlorine pill. Users may need to calculate the treatment based on weight with 1 pound of chlorine tablets per 10,000 gallons of water if the tablets are cracked or chipped.
The pool vacuum and filtration equipment cannot completely maintain crystal-clear pool water. Your pool can be made safe for everyone by adding chlorine up to a particular level, which will kill any bacteria, algae, insects, or other harmful organic material that may be present. However, you must search for the top chlorine tablets on the market and then base your choice on the factors listed above.
